Cheers Rainy, sounds like a great trip! I assume you will spend at least the whole summer on it.
I bought a pass (in '84) on an airline for 30 days and went to New Orleans - Seattle - Portland - San Diego - LA - San Fransisco - Washington DC. I can tell you that 30 days was way too short for that, even though I was flying all the way.
It is not a country, it's a continent. Flying from 40C in New Orleans to 10C in Seattle wearing shorts made that clear.
I loved all cities but New Orleans and San Diego stood out, and of course New York where I lived at that time.
I still dream of doing it again, but in a cadillac convertible!
